The linear canonical transform (LCT) is a versatile integral transform that generalises classical transforms such as the Fourier, fractional Fourier, and Fresnel transforms. By utilising four ...

SIAM Journal on Numerical Analysis, Vol. 33, No. 4 (Aug., 1996), pp. 1534-1558 (25 pages) We are interested in the study of a fast algorithm introduced by Brenier computing the discrete ...

The equation of motion of a discrete linear system has the form of a second-order ordinary differential equation with three real and square coefficient matrices. It is shown that, for almost all ...
